FREDERICK H. KNAPP, OF BALTIMORE, MARYLAND.-

HUSKING MACHINE.

Application filed August 4, 1919.

T 0 all 'wtomz't may concern Be it known that I, FREDERICK. H. Knapp, citizen of the United States, residing at Baltimore, in the county of Baltimore City and Sta-te of Maryland, have invented certain new and useful Improvements lin Husking Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to husking machines, and more particularly husking machines of the rotary type having a series of pairs of cooperating husking rolls or the like, which, in the movement of the carrier for the rolls about its axis, are adapted to constantly changepositions whereby to be brought into proper operative association with the corn to behusked.

ln machines of they character uncer consideration, it has also been ascertained that the initial shock on the corn when contacting with the husking rolls is often-times considerable, and has a tendency to bruise or otherwise damage parts of the corn, and it is a further object of the present invention to provide eiiiective means to overcome the above tendency.

lWith the above and other objects in view, it is contemplated herein to provide a husking machine having husking rolls of novel construction and associated means whereby the rolls may have the necessary yieldability to protect thel corn and at thesame time properly and effectively perform their husking function, and in carrying out this feature of the invention it is also proposed to make possible the utilization of liusking surfaces of relatively hard or wear resisting properties, thus prolonging the life of the machine and making unnecessary renewal of rolls as frequently'as has heretofore been I the case.

A. further object of the invention is to provide in a rotary type of husking machine Serial No. 315,080.

and a rotatable drivinrr head operatively associated with the rolls and adapted to impartA the necessary rotatable movement thereto and also being operatively associhead and drum, the parts being arranged,

and constructed with a view to simplicity, higher efliciency and reduction in noise, strains and vibrations of the parts..

Still other improvements, and novel details in the construction and arrangement of parts will be appreciated from the description toffollow, though it is to be borne in mind in this connection that I have in contemplation various alterations in details, all in keeping with the spirit of the invention.

The ,following description is to bel considered in connection with the accompanying drawings, which form a part hereof, and wherein is disclosedfor tliepurpose of illustration, a Vconvenient and satisfactory embodiment of the invention.

In the drawings,

Figure 7 is a transverse sec-tion of the same.

Figure S is a transverse section of a pair of husking rolls, 'one of which takes the form of a modification.

With more particular reference to the drawings, wherein like reference numerals refer to correspondin,9,` parts throughout the several views, a suitablev framework is provided, consisting primarily of standards,

taking the form of castings l and 2 positioned respectively at opposite ends of the machine and connected to one another as through the medium of supportingrods or bars 3, any number of which may be employed so as to afford a substantial and rigid machine framework. IThe framework is preferably so constructed that the machine may be moved with regard to the supporting surface, and whereby to permit the husking members proper of the machine to assume an inclination towards the discharge end thereof. llith this end in View a convenient means for accomplishing the above object is illustrated herein, and may be briefly described as follows. @ne end of the machine is mounted upon wheels or rollers 4 supported in any suitable manner from the casting 2 and adapted to normally rest, when the machine is in operation, upon a supporting` block or blocks 5, having in the upper surface thereof a segmental recess curved to correspond with the curvature of the wheels 4, whereby to constitute a restraining` medium for the wheels and to retain this end of the machine in stationary position. The opposite end of the machine is conveniently provided with a supporting block 6 extending transversely of the casting 1 and secured thereto in any desired manner, and the thickness of lsaid supporting block being preferably less than the diameter of the supporting` wheels 4 plus the thickness of the supporting block 5 whereby that end of the machine having the supporting casting l will be positioned slightly lower than the opposite or feed end of the machine. in this way the huslring rolls, to 4be hereinafter more particularly described, will assume a slight downward inclination from the feed to the delivery end thereof. This inclination of the rolls may be adjusted as desired, or the delivery end of the machine may be raised to a position so as to cause the rolls to assume a horizontal plane, in the event no inclination is necessary or desirable, by the interpositioning of suitable spacing` block-s T between the supporting blocks 6 and the surface. lt is understood of course that these blocks 7 do not constitute fined pL rts of the machine and may be removed as desired or other similar blocks added. Should it be desired to move the machine from place to place the supporting blocks 7 may be taken advantage of as a fulcrum for a` suitable tool or bar in the elevation of this end of the machine, and when elevated, the wheels 4 at the other end of the machine may, under force, be readily disengaged from the retaining block 5 whereby to permit the machine to move, through the medium of the supporting wheels 4, to any desired place.

The upright supporting castings l and i2 have a substantially circular cutout part as illustrated more particularly in Figs. S, 4 and 5 of the drawings, whereby to aord a substantially unobstructed opening at opposite ends of the machine to facilitate the entrance and removal of the corn. Positioned between the upright supports 1 2, is a rotatable drum or husking reel having annular end rings 8 and 9 respectively, which may be secured. to one another as through the medium of supporting rods or bars 10.

The huslring rolls, to be more particularly described in detail, are preferably arranged in pairs, a circumferential series of which are illustrated, and the number of which pairs may vary to obtain the best desirable results, according to existing conditions. These huslring rolls are supported from the annular rings 8 and 9, as previously noted, and in order to preventI longitudinal sidewise movement of the drum, assuming that the delivery end thereof inclines downwardly, l provide a suitable detent or end thrust bearing, taking the form of a roller 9, supported from a, suitable bracket 9b, project--4 ing laterally from the upright or standard 2. Preferably the roller 9a and bracket 9b is duplicated at opposite sides of the machine and by engaging the side of the ring 9 or a partixed thereto, an efficient end thrust bearing for the latter is afforded.

Projecting inwardly from the rings 8 and 9 are a series of relatively short brackets ll and extended brackets l2, a short and longbracket being provided for each pair of rolls. Supported from the short brackets ll are shafts 13, whereas supported from the lons/ger brackets l2 are shafts 14. Super-ted on the shafts 13 and i4 are tubular huskinf;` surfaces conveniently taking` the form of metal cylinders or tubes, though in this connection rubber or other means may be su`o stituted. Metal or other material of wear resisting properties are desirable, however, and because of the novel means of support therefor provided by me rollers of this type constitute satisfactory and efficient huslring members. l5 designates the huslring rolls on the shafts i3, and f1.6 the huslzina` rolls on the shafts i4. rlhese rolls are of greater diameter than their supporting shafts, and in order to permit the rolls themselves to have proper yieldability laterally in all directions, it is proposed to insert between the shaft and rolls a yieldable support. The yieldable support may take various designs and formations, such as springs or the like, but in the preferred ein-- bodiment of the inventiomthe yieldable supporting means is internal so as to be protected and not interfere with the husking operation, and a preferred means of support illustrated herein comprises cushions 17, conveniently of rubber or rubber composition forced. into place so as to frictionally engage icc lll@

)liti the shafts and metal tubes. These cushions terminate short of the ends of the rollers, and interposed between the rollers and shafts are suitable filler blocks taking the form of non-yielding (as metal) collars 18, which may begsecured in place asby pins projecting from the rollers and loosely passing through the collars so as to permit of the necessary movement between these parts. These collars are of less diameter than the husking tubes whereby to provide an intervening space 19 between the tubes and the collar at this point. -These spaces allow for the necessary movement of the husking rolls under.

compression, and the filler blocks limit such movement orplay and at the same time constitute retaining means forthe cushioning members. lhile, as previously stated, each of the cooperating` rolls of each pair maybe similarly supported, l'havefound that very satisfactory results may .be accomplished by supporting one only of the rolls of each pair in the manner just described, whereas the cooperating roll may berigidly supported or take the form of a solid roll with a rubber or metal periphery, and a convenient type of cooperating roll is illustrated in Figure 8, taking the form of a metallic tube v15a supported from a rotatable shaft 13a, and interposed between the metallic tube and shaft are suitable metallic washers .or filler members 1Sa engaging and connecting respectively with the shaft and surrounding tube whereby to firmly support the latter against relative lateral play. In this latter type of construction, the non-yieldable husking roll presents al more-or less firm engaging surface and thecooperating yieldable roll will in most instances supply the necessary yieldability between the rolls during the husking operations, but if, as desired,

still further yieldability may be found advisable all of the rolls throughout the vseries may have independent yieldable characteristics. i i

Preferred mechanism for vimparting rotatable movement to the cylindrical drum or reel, and independent rotation to the husking rolls proper will now be described.v A main driving shaft 2O is provided, the same being mounted in suitable vbearings in the casting 2 for rotatable movement, and conveniently of a length to project to the opposite end casting .1 and having a suitable bearing in the latter. The shaft 20 is adapted to be driven from any suitable source,.and in any suitable manner, a simple type of drive being illustrated and taking the form of a pulley or sprocket 21 adapted. to have rotatable movement imparted thereto as by means of a belt or chain not shown. 'Positioned on the shaft/20 for rotatable movement therewith is a suitable pinion 22 adapted to mesh with external gear teeth 23 on the ,lisc-shaped'gear wheel yor rather ring 24,

Secured to one side of the ring` 24C as by means *ofv retaining pins` or'the like 25 is an auxiliary ring shaped member 26 o-ffla .diameter preferably slightly: less than the diameter of the gear ring 24,. and conveniently having in the periphery thereof a central guideway or groove 27, the periphery of said ring 26 constituting a circular track or runway surface for the parts comprising the rings 24 and 26. Secured .to the traclrring 26 and preferably constitutingan integral extension thereof is an annular flange 27 having internal gear teeth 28. Mounted upon the shafts 13 for the husking rolls 15l are suitable pinions 29 arranged to ymesh with the'internal annular gear2Z-28. Also mounted upon the shafts 14 of thefhusking rolls 16 are pinions 30 adapted tomesh with, the pinions 29, and because of the fact that the relatively long supporting brackets 12 position the shafts 1-1 at a point inwardly with respect to the shafts 13, the pinions 30 will likewise be positioned inwardly or at i a point out of contact with the internal 'gear teeth 2S. vT he intermeshing pinions 29 and 3() are adapted to impart rotatable move.`

ments to the rolls of each pair in opposite directions through the medium of the rotatable annular gear member 27--28- Itis desirable to simultaneously rotate the drumy or cylinder which carries the husk-` head, comprising 'the members wheel31 is a gear wheel 33 mounted upon ,Y

a suitable shaft 34 supported from theuprights or standards 1: and 2 forrotatable` movement. The gear wheel33 through the gear wheel 31 is adapted to rotate the shaft 34, and mounted uponsaid shaft 34 isa suitable ydrive pinion 35 adapted to mesh with an annular gear wheel S'xedin any f desiredmanner to one of the end rings of the drum, preferably. the inner end ring '9. The' gear wheel Sois `preferably of a 'diameterv slightly greater than that of the end ring 9, andI the periphery of this ring 9 constitutes a trackway. This is also truel of the periphery of the end ringv member 8.

At the top of the machine and projecting between the uprights 1 and 2 andfsupported therefromfor rotatable movement `is 'a shaft 36, and mounted upon said shaft is a suitable roller 37 having a'central peripheral flange 38 ada )ted to engage in the `Ofroove 27 .'a l i D of the annular treadway 26 for said roller 37.1 A lso positioned on said shaft-for rotat-A f 'able movement with the latter are anti-friction rolls 39 anda() adapted to engage reiso lso

spectively the periphery or annular tread surfaces formed by the rings 9 and 8 respectively of the drum. Supported for free rotatable movement are suitable rollers 4l and 42 adaptedto engage the periphery of the end rings 8 and 9 adjacent the base and to one side, and adapted to engage said members 8 and 9 adjacent the base to the opposite side are rotatable rolls 43 and all, the latter being supported preferably from the shaft 3% but independently rotatable. The shaft 34 may also have mounted upon a projecting end thereof for relative free `rota-tion a roll l5 to engage the trackway 26 of the driving head adjacent the base and to one side, whereas an auxiliary roll 46 conveniently on the shaft 2O forrfree ro` tatable movement is adapted to engage said trackway 26 adjacent the base the oppositeside of the machine.

The corn to be husked is adapted to be delivered into the chamber formed' by the rotatable drum in any suitable manner as by positive movable feeding mechanism, or as illustrated in the drawing through the medium of a suitable trough or receptacle 1-7 open at the top 48 thereof and having an inclined base or chute part 49 and a projecting delivery end 50 adapted to extend through the opening formed by the annular gear 3l and hub 32 to a point adjacent the feed end of the husking rolls.

lt may be desirable at times to relatively adjust the husking rolls, and to this end one of the bracket supports, say-l1, may be mounted for adjustable movement as through the medium of a curved slotted way lla' through which the retaining bolt 1lb passes, and in this connection the retaining bolt illc will constitute a pivot when the bolts areloosened7 and when the brackets are properly adjusted to take up play, etc., both of said bolts are threaded into seated or retaining position.

W'hile in some instances it may be desirable to have a substantially continuous series of pairs of husking rolls onthe drum, it has been ascertained that for some purposes this is unnecessary, particularly in view of the rapid rotation of the drum, and for this reason l prefer to have the pairs of rolls spaced from one another and to provide in the intervening spaces suitable filler members constituting in connection with said rolls a substantially vcontinuous engaging orsupporting surface for the corn. These filler members may take various forms, but in the illustrative embodiment of the invention, ll find it convenient to einploy segmental plates 5l arranged adjacent the active periphery of the rolls and eX-v tending longitudinally of the latter and secured in position in any desired manner, as by flanges or brackets 52 to the end rings 8 and 9 respectively.

The construction and operation may be briefly reviewed as follows:

Assuming that power has been applied to the driving pulley 21, the driving head, comprising the parts 24-26 and 97 are rotated through the medium rof the interposed pinion 22 and gear teeth 27. rllhe rotation of the head through the medium of the internal annular gear 28 and the intermeshing gears 29 and 30 impart the necessary rota-- tion to the husking rolls, it being noted in this connection of course that the rolls of each pair rotate in an opposite direction. At the same time, rotatable movement .is imparted to the drum through the medium of the gear connections 3l, 33, 35 and 36, but at a different speed from that of the driving head proper.

The ears of corn may be continuously fed into the machine through the chute at the feed end thereofy and discharged at the opposite end of the machine after the husking operation, and any suitable delivery chute or the like may be employed in this connection or the husked ears may be directly deposited onto the floor or suitable .receptacle or conveyor.

ln view of the rotatable movement of the drum it will be observed that the husking rolls are continuously changing their positions with the result that regardless of how the corn may be supplied to the drum the husks will sooner or later be. engaged between the rolls of one or another of the several pairs of husking rolls, and in this connection it has been ascertained that when the rolls of each pair are offset with respect to one another as illustrated, the bushing operation is materially facilitated.

In view of the yieldable characteristics of the husking rolls proper, this eliminates to a large extent noise, but what is perhaps most important, the sudden shock on the ears when first brought into contact with the husking rolls is largely overcome with the result that the ears or rather the corn, will not be damaged incident to the husking operation.

rlhe construction of the present machine, because of the elimination of many gears7 chains and the like, previously employed, is not only rendered less expensive in operation and upkeep, but also eliminates to a considerable extent noise in operation.

By reason of the frictionally engaging rollers for the driving head as well as the drum, which rollers engage annular trackways on these parts, considerable strain on the operating gears is eliminated, and the parts are firmly supported against unnecessary vibration and undue strains. This characteristic also is of importance in deadening sounds. The frietionally engaging rolls which contact with the tracks of the husking drum are also of importance in llO their tendency to prevent overriding of the drum under the action of the gears in op-A eration. Y
